Legrand 2P 16A 30mA RCBO (DX3) – residential

The Legrand DX3 RCBO DP 16A 30mA is a dual-pole safety device engineered for residential final circuit protection. It integrates residual current detection (30mA Type AC) and overcurrent protection (16A Curve C) into a single 2-module DIN rail unit. This BIS-certified breaker monitors both live and neutral lines to prevent earth leakage, short circuits, and overloads.

Quick Answer

Yes, you should invest in the Legrand DX3 2P 16A 30mA RCBO for critical residential circuits. It combines 30mA earth leakage and 16A overload protection in one compact unit, crucial for preventing electrical shocks and fire hazards in Indian homes. Its BIS certification and 10kA breaking capacity ensure robust, compliant safety, providing complete peace of mind.

✓Protects human life from direct contact shocks — 30mA residual current sensitivity.
✓10kA breaking capacity manages high-energy short circuits without device failure.
✓Space-saving dual protection in one unit — 36mm width fits standard 2-module slots.
✓Instantaneous tripping class ensures power is cut in ≤300ms at 1x rated leakage.
✓High mechanical durability for long-term reliability — rated for 10,000 cycles.
✓IP20 degree protection ensures safety against accidental finger contact with terminals.

This Legrand DX3 2P 16A 30mA RCBO is ideal for homeowners prioritizing ultimate electrical safety on critical circuits like geysers or ACs, ensuring complete protection against electrocution and overloads. Avoid if seeking only basic overcurrent protection; this device is engineered for comprehensive, dual-threat safeguarding.

Engineering Analysis
A 30mA sensitivity is essential for human life protection because it trips at a threshold lower than what causes cardiac arrest. The 10kA breaking capacity ensures the device can safely interrupt high-magnitude fault currents at the distribution board level. The 2P configuration provides complete isolation of the circuit by switching the neutral, which is vital for safety in modern Indian residential wiring.
